Seven months of heat, and nights near 28 degrees
Glassboro homes run their furnace from October through April. That's seven months a year, and on winter nights that average 28°F, the furnace is doing real work, not just taking the edge off.
Most homes here heat with gas, so a new furnace has to meet the federal minimum of 80 percent AFUE if it's a non-weatherized model built after November 2015. Gloucester County has had 15 winter storms and 140 damaging wind events over the past ten years, and across New Jersey, 11 percent of households lost power for at least 24 hours in 2024. Most furnaces start back up on their own once power returns, which matters when storms like these knock it out.

New Jersey requires HVAC contractors to hold a state license.
The license comes from the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. It covers the contractor, not the job itself. The person or business doing the work has been tested and is on record with the state. Towns and cities in New Jersey are not allowed to layer their own license on top of that. The same rule applies whether the address is in a city or out in the county.
For a furnace installation, the state license is what stands behind the contractor's qualification to do the work. The local building office is what stands behind this specific job. It issues a permit and does an inspection once the furnace is in, checking that the installation itself was done right. Most homes in Gloucester County heat with gas, and the gas connection is the part of the job where a mistake matters most. That inspection is where a bad connection gets caught.

- What size furnace does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor measures your insulation, window area, ceiling height, and how much outside air leaks in, then works out how much heat you lose on a cold night. Get this wrong and the furnace either short cycles because it's too big or runs constantly and still can't keep up because it's too small. With winter lows here averaging 28°F, that calculation matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a jump in your gas bill without a jump in usage. Rust near the burner or a yellow flame instead of blue both mean a problem worth having checked right away. Age matters too. A furnace working hard for 7 months a year, every October through April, wears faster than one that only runs a few weeks a season. If yours is old and needs a repair call every winter, replacing it is usually the better move than paying for another fix.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're replacing. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so even a standard furnace today wastes less fuel than an old one might. A high-efficiency model goes beyond that minimum, sending less heat out the flue, which matters more here with a heating season that runs 7 months a year. A contractor can walk you through the options and price out what each one would mean for your specific house.
